ture. The proper combination
of
shutter and aperture settings

Th
e necessary settings will be
based upon the
ISO
speed set for the film in use and the
operation of
th
e camera's exposure control syste
m.
The relationship between aperture and shutter
is
as follows:

Se
lecting
th
e exposure control mode means deciding if you
want the shutter speed/aperture to be set automatically or
manually.
The Nikon N6000 offers five modes: four automatic exposure
control modes - Auto Multi-Program
(i:d), Normal-Pro-
grammed
(fj),
Shutter-
Pr
iority auto
(~),
and Aperture-Priority
a
ut
o (.BJ) - in addi
ti
on to Manual
(111)
mode.
Each exposure mode h
as
its own advantages.
In
Pr
ogrammed auto exposure mode,
as
th
e optimum combi-
na
ti
on of
sh
utt
er speed and aperture is automa

In Shutter-Priority auto exposure mode, you can manually
se
t
shutter speed
as
desired. That
is,
you can freeze the ac
ti
on
with sharp, clear images using a fast shutter speed, or create
motion effects by choosing slower shutter speeds.
In
Aperture-Priority auto exposure mode, you can control dep
th
of field by varying
th
e apertur
e.
You
can use a larger aperture
(smaller f-number) for shallower depth of
fi
eld to create softer,
less distinct background
s,
or choose a sma
ll
er aperture (la
rg
er
f-numbe
r)
for greater depth of
fi
eld.
In
Manual exposure mode,
in
addition to controlling both shut-
ter speed and apertur
e,
yo
u can easily create intentiona
ll
y
over- or underexposed photos.
